FEEDING AND CREASING DEVICE.

Specification of Letters Patent.

Patented Aug. 11, 1914.

To all whom it may concern:

Be it known that I, HENRY B. OOOLEY, a citizen of the United States, and aresident of New Britain, in the county of Hartford and State of Connecticut, have invented a new and Improved Feeding and Creasing Device, of which the following is a specification.

My invention pertains more especially to machines for folding paper or like material and such as are commonly employed in connection with envelop folding machines, and an object of my invent-ion, among others, is to provide a device of this class that shall be adapted to operate upon envelops or like articles of various sizes.

One form of device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawings, in which Figure 1 is a view in front elevation of some of the rolls of an envelop folding machine showing my invention applied thereto. 1

Fig. 2 is a view in cross sectionthrough the frame of the machine on plane passing through the aXls of the creaslng rolls. Fig.

3 is a view in verticalcross section through the creasing rolls. Fig. 4 is a detaili view showing the creasing rolls in position to grasp a blank.

In the accompanying drawings the creasing rolls include one member having a: creasing groove to receive a creasing rib from the other roll, the numeral. 5 denoting the shaft of the creasing bar roll HD1126 the shaft of the grooved creasing roll, which rolls travel in cooperative relation, said shafts being suitably mounted in bearings of any ordl nary construction upon: the frame of the machine. These shafts have intermeshing gears 78 secured thereto and driven inany tatably, adjustably mounted upon the shaft 5. Screws 14 may be employed for securing the feed roll to theshaft, and screws 18 for securing the creasing bar rolls to the shaft. The feed roll is cut away, as at 15-,

for a portion of the distance about its periphery, the advance edge 16 of the full portion of the roll forming a grab between which and the roll 10' the envelops or like articles are grasped and moved along. In securing. the feed roll and creasing, bar rolls to the shaftfsplit bushings 19 are located between the rolls and shaft 5, andthe screws 14 and 18 impinge upon these bushings. A groove 20 is formed in the fullest portion of the feed roll 13.

Recesses 21 are formed in each of the creasing bar rolls 17 in which recesses a creasing bar 22" is secured, extending from one of the creasing bar' rol-ls to the other across the cut away part 15 of the feed roll. This creasing bar is secured in any desired manner, and it has a rib 23 formed to enter the groove 11 for the purpose of" forming a crease in an envelop or like article passing between the rolls.

Different sizes and varieties of envelops or like articles cause the crease or creases to be located in different positions with respect to the advance edge of the envelop, and in order to enable these creases to be located in proper position on the envelop it is necessary that the creasing devices may be located indifferent positions, and in loeating these devices in different positions it, of course, is essential that the roll bearing the crease shall register with that bearing the creasing bar. In order to simplify the adjustment of the parts in arranging the creasing devices for any special work I employ sleeves 2t25 mounted on the shafts 56 respectively, these sleeves being secured to the rolls as'by means of screws passing through flanges 26. Each of these sleeves have intermeshing gears 27- secured thereto, which gears are of such size and have the teeth so formed thereon that they will freely intermesh when the two rolls are rotated in unison as compelled by the gears 'Z and 8.

The rolls above described are mounted in side parts 28 of the machine and supply rolls 29-30 may-be employed todeliverthe envelops to the creasing rolls, and rolls 31 to take the envelops away from the creasing r0lls.- Any suitable means for supplying the creasing rolls may, however, be employed, and my invention i not therefore necessarily restricted to any particular means for feeding the envelops. When such supply rolls are employed the periphery of one of them will be cut away, the roll 30 being shown herein as so cut away at 32 and the supply rolls, or other means that maybe employed to deliver the envelops to the creasing roll will be so arranged and operated that the envelops will be delivered to the creasing roll in a predeterminedposition with respect to the grab on the creasing members. The cut away part32 is-provided for the purpose of enabling the rolls to instantly and surely grasp the envelops, and thus insure uniformity of feed and avoid any slipping back of the paper in the wedging action of he rolls'and before the edge of the blank is grasped by the rolls, and the distance from the advance edge of the uncut away part of the roll 32 to the rear edge thereof will be sufficient to feed the envelops into the space between the cut away portion 15 of the feed roll 13 and the creasing roll 10, which latter rolls will be in this relative po sition at the time the envelop is presented to them. The rotation of the several rolls will be properly timed with respect to one another to present the advance edge of the envelops into this space between the creas ing rolls just before such space is closed, and the distance from the grab 16 back wardly to the rib 23 will be substantially the distance from the advance edge 33 of the envelop to the line 34 to be creased, when the advance edge 33 is presented between the rolls substantially coincident with the grab 16; lhe position of the envelop is shown in dotted'lines in Fig. 1, this style of envelop being subsequently creased on the dotted lines 35, from which it will be seen that the flaps 36 travel on the creasing bar rolls 17, the advance edge 33 of the envelop determining its proper position with respect to the rolls.

It is essential that the groove 11 and the rib 23 shall always be so relatively located that the rib will enter the groove in the rotation of the rolls. I-t becomes essential to frequently change the location of the creasing'bar and the rib 23 thereon, by reason of operations upon difierent sizes of envelops, and the construction preserves the proper relative arrangement of the groove and rib at all times, during such adjustments.

While I have shown and described herein a satisfactory arrangement of parts for accomplishing the desired result, this may be departed from to a greater or lesser degree and yet be within the spirit and intent of the invention.

I claim:

1. A pair of creasing rolls, one of said rolls having a groove and the other inchul ing a shaft, a feed roll secured to the shaft and having a cut away portion forming an advance edge to grasp a sheet, creasing bar rolls secured to the shaft at opposite ends of the feed roll, and a creasing bar secured to the creasing bar rolls and extending across the cut away portion in the feed roll and having a rib to mate with the groove in the opposite roll.

2. A pair of creasing rolls, one of which has a groove and the other of which includes a shaft with creasing bar rolls secured thereon, a feed roll mounted between the creasing bar rolls and movable independently thereof for adjustment purposes and cut away on one side for a portion of the distance around its periphery, and a creasing bar secured to said creasing bar rolls and extending across said cut away portion of the feed roll and having a rib arranged to mesh with said groove.
